NAME

sane-umax1220u - SANE backend for the UMAX Astra 1220U scanner

DESCRIPTION

The sane-umax1220 library implements a SANE (Scanner Access Now Easy)
backend for the the UMAX Astra 1220U scanner.
For the latest information on this backend, please visit

UMAXASTRA2000UEXPERIMENTALSUPPORT

This backend may also be able to drive the UMAX Astra 2000U. Some
people are successful with it, others report that the colors come out
terrible. Your milage may vary.
From Stephane (the author of sane-umax_pp), I learned that there are
differences in the way the color calibration is performed on the 1220U
and the 2000U and it may account for the problem. Stephane’s backend
support the 2000P, the parallel port sibling to the 2000U. It may be
possible to use ideas and code from Stephane’s backend to add complete
support for the 2000U to this backend. Since I do not have access to an
Astra 2000U, I do not plan to work on this - any volunteers?

CONFIGURATION

The configuration file for this backend resides in
/etc/sane.d/umax1220u.conf.
Its contents is a list of device names that correspond to UMAX Astra
1220U scanners. Empty lines and lines starting with a hash mark (#)
are ignored. A sample configuration file is shown below:
#usb vendor product
usb 0x1606 0x0010
# Device list for non-linux systems
/dev/scanner
/dev/usb/scanner0
When driving a Astra 2000U, use the product number 0x0030. See sane-usb(5) for information on how to set the access permissions on the usb
device files.

FILES

The backend configuration file:
/etc/sane.d/umax1220u.conf
The static library implementing this backend:
/usr/lib/sane/libsane-umax1220u.a
The shared library implementing this backend:
/usr/lib/sane/libsane-umax1220u.so (present on systems that
support dynamic loading)

KNOWNBUGS

600 dpi scanning may fail for large image sizes.
If you keep getting I/O errors, try cycling the power on your scanner
to reset it.
There is no way to cancel a scan, since the driver ignores
sane_cancel().
If you try scanning an image which is too small, you will get I/O
errors. Be sure to adjust the scan area before doing a scan, since by
default, the scan area is zero.
